hey guys, been checkin out this forum for quiet some time now, definately where all the experts are. Was hoping somebody could help me.

I have been having nothing but grief with my trans. I got a rebuilt done on it with best of the best stuff. Red eagle clutches/kit, super servo, beast shell, oversize valve, 13 vane pump upgrade, all the bells and whistles. Well I put the trans in, after a week it screwed up again. Took the trans out, and some other part got a crack in it, i believe the pump, or something. Fixed it up put it back in, and the damn thing blew up again within the week. Basically it wont hold any pressure during a shift. If u stay on the gas it will clunk into a shift, rev out, go nowhere until the rpms come down, then something enganges and the car is under power again. SO basically for it to shift into the gears without a messed up clunkin sound coming, u have to drive it like a manual. Accelerate till its about to shift, let off the gas, wait for the shift, then get back on the gas. This needs to be done otherwise it just seems like damage is goin on otherwise.

Well thats the story, today I stand at obtaining another 4L60E it is out of a impala i believe. I looked at it, everything looks the same except for the tail shaft housing. Is this trans gonna be fine to do a swap? or do i need to adjust driveshaft or anything else along those lines. Can i take off the tail shaft housing off the existing trans, and put it on the replacement 1? Any help i will greatly appreciate, thanks guys

 

Yes, you can just swap the tailhousings. It's only a metter of (4) 15 MM bolts. The biggest concern is to make sure both transmissions are the same year.

Why isn't the person who built your "performance" unit standing behind it? It still amazes me what some people sell. it sounds like someone messed up pretty bad.

lol u dont even want to get me started on telling u the whole story. Thanks for the quick reply Frank. But to make a long story short. The prob is Im out in canada. I even believe i spoke to u, or your some1 at your place when i was doing the whole transmission research. I told you about the stuff i was getting and u basically confirmed it. As fas as i was concerned I had the best of the best "performance" parts. Well the damn guy who i thought was supposed to be a pro builder, told me i supply the killer parts and he will build it, with a so called "Warranty" cuz he also said the parts where the best. Thats the main reason I didnt have my trans built from u in the first place. Well the local guy built it, and something else supposedly went, he showed me the part, and for sure it wasnt something i replaced. So honoring that so called warranty, he fixed it, but jeez man, my motor killed the trans again. Im sick of dropping and installing trans, so i found this used 1, and im concerned about the year now. I was just basically gonna replace it so i can drive my car, i couldnt even get chance to experience to new build cuz of the trans. I was gonna grab the trans guy out here by the throat and deal with it, and in the meantime was gonna send out that trans to u. LOL sorry bout the rant, but as u can c, im pretty choked bout the whole thing, so im really hoping i can use this impala 1 while i deal with the supposed "performance" trans.

Sooo quick question. How can i check year, or using measuring tape is good enough? The reason for tail shaft housing swap is because right of the bat i noticed that my speed sensor i believe is way different than the 1 on the impala 1. Is the year concern to do with the pcm at all? cuz I have tunercat and pcmforless subsciption. Im sorry to say man, but all the trans guys out here are peices of ****. believe me I went to two shops and if i told u the story u would shake your head. Basically every1 thinks they know these cars out here, when nothin could b furthur from the truth, u vendors out in the US are the best, thats Y im glad u already replied to me, cuz i was gonna b calling u anyway lol, thanks again man sorry for the venting out . appreciate the response.

 

frank its out of a 96, is that gonna be a prob? thanks.

 

'95 and '96 use different 3-2 solenoids, and valve arrangement. I've seen people change the solenoids, but I've seen that cause forced downshift problems.

noooo. Forced downshift? is that me manually downshifting? Sorry man i dont know much bout trans. So do I need to return it or can it be used somehow? Is there any markings I can find out wat the deal is with this trans, i believe it has a huge K on the side. haha

"forced downshifts" are normally referred to as "kickdown". It's when you jump in the throttle and the transmisson downshifts.

Is the white paper tag still present on the bellhousing? If so, the first digit reflects the last gigit in the production year. A '96 transmission also has a small diameter speedo, on the passenger side. A '95 unit will have a large diameter one on the drivers side.

thanks again for the replies. Theres no sticker left on the trans. Thats why I was asking about changing the tail shaft housing. Other than that the trans looks identical. Do i 100% need to change the 3-2 solenoid? Can it be after I install the trans or do it before? If I manualy downshift the 3-2 will it still go into gear or will it stay in 3rd? Thanks again man.

 

frank is they swap pretty straight forward? is their an indication as to which the 3-2 solenoid is?

 

The 3-2 solenoid limits flow to the 3-4 clucth during this downshift. It is a very straight forward swap. As for functionality it may cause harsh or soft 3-2 shifts , The transgo kit actually blocks the valve this afects so I dont think it will be a major issue, I have done it but Have not had the opuritunity to compare side by side the affect but it seemed fine to me and did not cause any issues I could detect. The car has been in service 3 years now

 

thanks for the reply. Well this is wat i ended up doin. I replaced the whole wiring harness, along with the 2 solenoids on the end of the valvebody. I think it is the 3-2 solenoid and the pmw solenoid. Is this good to go? Also i have some crazy super servo on the 95 trans, can I replace just this thing with the 96, or will it cause problems? Thanks again guys. Oh ya and i just replaced the tail shaft housing with the 95 1, bigger speedo.

sorry 1 more question, I had a 2800 stall in the 95 trans, the 96 came with its stock converter. The 95 trans stank when I opened it up, can the stall be reused, flushed or something, without cutting it, is it worth it, or can I just use the stock 1 with all my performance mods. I dont wanna start dumping money in this 96 trans, I just wanna b able to drive the car, while I figure out which route im taking with the actual 95 trans. Do I need to send it in to u guys to get it worked on or u guys have the core?

 

Well in our case we have the core so you would send us nothing , As for the servo may be worth it to swap its easy and wouldfirm up the shift queit a bit on the 96. Normally I would be agaist uning the converter from the other unit but if you drian it and carfully inspect what in it and there are no debris then have it flushed you may be on since your swapping used for used anyway, But that would haveto be your call .
